Kyamarar gama gari akan wayoyi masu wayo shine MIPI, kuma wasu kyamarori (kamar wasu kayan aikin da ke goyan bayan dubawar DVP) sune DVP.
MIPI gajere ne don Interface Mai sarrafa Masana'antu ta Wayar hannu (A takaice, USB yana nufin Universal Serial Bus, MIPI yana nufin Interface Mai sarrafa Masana'antu ta Wayar hannu, DVP tana tsaye ga tashar bidiyo ta dijital, CSI kuma tana nufin CMOS Sensor Interface.
1.DVP dubawa
DVP bas PCLK iyaka na kusan 96M, kuma tsawon layin ba zai iya yin tsayi da yawa ba, matsakaicin adadin duk DVP shine mafi kyawun sarrafawa a ƙasa da 72M, shimfidar PCB mafi sauƙin zana.
DVP tashar jiragen ruwa ce ta layi daya kuma tana buƙatar PCLK, VSYNC, HSYNC, D[0:11] - na iya zama bayanan 8/10/12bit, dangane da tallafin ISP ko baseband.
Sashin fitarwa na DVP: VSYNC (siginar daidaita tsarin firam), HSYNC (siginar daidaita layin), PCLK (agogon pixel), layin bayanai (8-bit ko 10-bit) - ainihin bayanan RGB da aka watsa.
2.MIPI dubawa
MIPI shine watsa tashar tashar jiragen ruwa daban, saurin sauri, tsangwama.Modulolin wayar salula na yau da kullun suna amfani da watsa MIPI.
Kyamarar MIPI tana da wutar lantarki guda uku: VDDIO (ikon IO), AVDD (ikon analog), DVDD (ikon dijital na kwaya), nau'in firikwensin firikwensin wutar lantarki daban-daban, AVDD yana da 2.8V ko 3.3V;DVDD gabaɗaya yana amfani da 1.5V ko mafi girma, ƙirar masana'anta daban-daban.
Ƙarin bayanin kula: MIPI dubawar kyamarar ana kiranta CSI, kuma MIPI nunin dubawa ana kiransa DSI.
Ƙungiyar MIPI (Mobile Industry Processor Interface) Alliance ƙungiya ce ta fitar da ƙayyadaddun ƙayyadaddun mu'amalar CSI-2 akan siriyal ɗin kyamara.
Ƙididdigar MIPI CSI-2 tana amfani da ƙananan albarkatu daga CPU - godiya ga masu sarrafawa da yawa.Tsohuwar ƙirar kyamara ce don Rasberi Pi da Jetson Nano.Tsarin kyamarar Rasberi Pi V1 da V2 suma sun dogara da shi.
MIPI buɗaɗɗen ma'auni ne na masu sarrafa aikace-aikacen wayar hannu wanda MIPI Alliance ya ƙaddamar, kuma ka'idar MIPI-CSI-2 ƙayyadaddun ƙa'idar ce ta MIPI Alliance, wacce aka kera ta musamman don haɗin guntun kyamara.
